3rd time

This is my third time trying and I got a pip! its started 6 am and now its 4 pm has not come out yet. The hole is now the size of a dime. The humidty is 21% I can't seem to increased it. should I worry? she is still peeeping. I also have another one pipped just now !!

Last spring I had one who pipped and then didn't come out for what seemed like forever. In the meantime they were hatching all around her. She actually got more aggressive and came out after she heard all the peeping around her.
